Unincorporated Minnehaha County, South Dakota requires a building permit for new construction, additions and most structural work, issued by the Minnehaha County Planning and Zoning office12. The county has had countywide zoning since 1990, with most rural land in the A-1 Agricultural District3. Septic systems also need a county-issued permit, but only a South Dakota-certified installer can pull it45. Recreational vehicles cannot be used as year-round housing here, though a mobile home can sit on your land temporarily while you build2.

Do you need a building permit in Minnehaha County, South Dakota?

Yes. Minnehaha County requires a building permit for any work regulated by the International Building Code as adopted by the county, and it is unlawful to start that work without one2. The Minnehaha County Planning and Zoning office issues both building and zoning permits and inspects new construction for compliance with building, plumbing and sanitation codes19. If you are building a new single-family home in the A-1 Agricultural District, the county also requires a Right to Farm Covenant to be filed on the parcel before it will issue the permit2. The county's permitting rules (Article 23.01-23.07) were amended May 26, 2026, so confirm current requirements with the office before you apply2.

Who is the Minnehaha County building department, and how do you reach them?

The Minnehaha County Planning and Zoning office handles building, zoning, septic, code enforcement and floodplain matters for unincorporated Minnehaha County9. Reach the office at (605) 367-4204 or visit 415 N. Dakota Ave., 3rd floor of the Administration Building, in Sioux Falls, SD 571049. The office is open 8:00 AM to 5:00 PM Monday through Friday, including the noon hour9. To obtain a building or zoning permit, you apply in person at that office and describe the work, the legal description of the land, and the proposed use2.

Does Minnehaha County have zoning?

Yes, Minnehaha County has had a countywide zoning ordinance since 1990, and it covers unincorporated land across the county3. Most rural land sits in the A-1 Agricultural District, where a new single-family home needs a building site of at least one acre, a 125-foot lot width, a 30-foot front yard (50 feet if the lot fronts a major arterial or section line road), 7-foot side yards, a 30-foot rear yard and a 35-foot height limit2. A-1 land generally gets one building eligibility per quarter-quarter section, and the county must approve access onto a public road before a home can be built there2. These are county rules for unincorporated land; a parcel inside Sioux Falls or another Minnehaha County city follows that city's own zoning instead3.

How do septic permits work in Minnehaha County?

Septic permits for rural Minnehaha County are issued by the Planning and Zoning office, but only to South Dakota-certified installers, not directly to homeowners45. Every installation or repair of a septic system outside city limits needs one of these permits, and all systems must be installed and repaired by state-certified installers5. Statewide, the South Dakota Department of Agriculture and Natural Resources sets the minimum on-site wastewater rules that county permits and inspections follow10. About 20% of Minnehaha County's soils rate without severe limits for a conventional drain field in the USDA soil survey, so plan on a site (percolation) evaluation and budget for a mound or engineered system on much of the county11. The county requires at least 10 feet between a septic tank and any building and 20 feet between a drain field and any building, and state rules put septic tanks at least 50 feet from a well over 100 feet deep (75 feet from a shallower well) and drain fields at least 100 feet from that same well (150 feet from a shallower one)5. If your site has no water or electrical service, South Dakota also allows vault privies without prior approval, and composting or incinerating toilets as an experimental system with a state-approved design12.

Can you live in an RV or tiny home on your land in Minnehaha County?

Not as year-round housing. Minnehaha County's zoning ordinance says recreational vehicles cannot be used as accessory structures or for human or animal occupancy, and an RV cannot be hooked up to gas, water, septic or sewer service without a county permit2. The ordinance does let you park or store recreational vehicles on a residential lot, including up to three that you don't hold title to, but that is a storage allowance, not an occupancy one2. If you are building a permanent home, you can place a mobile home or manufactured home on your own land temporarily during construction; placement cannot start until construction has actually begun, and the unit must come off within one year or when the new home is finished, whichever comes first2. A manufactured home can also become a permanent dwelling through a conditional use, but only if it was built on or after July 15, 1976, is at least 22 feet wide, and sits on a frost-protected foundation2.

Building a home in Minnehaha County: the steps, in order

  1. Confirm your parcel's zoning district and building eligibility with the Planning and Zoning office before you buy; in the A-1 Agricultural District a new home needs at least a one-acre building site and county-approved access to a public road2.
  2. If your lot is in the A-1 Agricultural District, file the Right to Farm Covenant on the parcel; the county will not issue a building permit for a new single-family home there without it2.
  3. Apply for a building permit and zoning permit at the Planning and Zoning office, 415 N. Dakota Ave., Sioux Falls, describing the work and the proposed use92.
  4. Line up a South Dakota-certified installer for septic; the county issues the septic permit to the installer after they test the soils on your lot5.
  5. If your driveway will connect to a county highway, apply for an access permit through the Minnehaha County Highway Department; if it connects to a state highway instead, the permit comes from the South Dakota Department of Transportation and construction can't start until that permit is issued1314.
  6. Schedule electrical and plumbing inspections with the state commissions, giving at least 72 hours' notice; a rough-in inspection happens before wiring or pipe is covered, and a final inspection is required before occupancy1516.
  7. If you're doing your own electrical work as the owner-occupant, get the homeowner wiring permit before work starts; it exempts you from the contractor-license requirement, not from the permit or inspection67.

What to check before you buy land in Minnehaha County

Water: a well needs a South Dakota-licensed driller, and a water-right permit is required only for certain proposed uses, so confirm with the state before assuming you can drill without one8. Soils: roughly one in five Minnehaha County soil types rates without severe limits for a standard septic drain field, so budget for a soil test and possibly a mound system on the rest11. Flood: a floodplain development permit is required for building in a mapped floodplain, and the Planning and Zoning office administers that ordinance for the unincorporated county179. Access: find out whether your road frontage is a county highway (typically 55 mph, Highway Department jurisdiction), a state highway (typically 65 mph, South Dakota DOT jurisdiction), or a gravel township road, since each has a different permit process for a new driveway18. Taxes: the typical effective property tax rate in Minnehaha County is about 1.2%, with a median annual bill near $3,0901920.

Watch-outs

  • Minnehaha County amended its building and zoning permit rules (Article 23.01-23.07) on May 26, 2026 under Ordinance MC16-189-26, so confirm the current permit process with the Planning and Zoning office before you apply2.
  • Don't plan to live in an RV on Minnehaha County land: the zoning ordinance bars using a recreational vehicle for human occupancy, and only a temporary mobile home during active construction is allowed2.
  • Confirm whether your road frontage is a county highway, state highway or township road before counting on a driveway-permit timeline — each is handled by a different agency18.
